Video games often track player scores. Given a list of scores, how do you find the best one? The worst one? The average? In this project you will write algorithms — step-by-step procedures — and put each one in its own function.

Your program must meet the following specifications:

• Define a function called find_highest that takes a list of numbers and returns the highest score
• Define a function called find_lowest that takes a list of numbers and returns the lowest score
• Define a function called find_average that takes a list of numbers and returns the average score
• Inside each function, use a for loop to look at every score

In find_highest and find_lowest, start by assuming the first score is the answer, then update it when you see a higher or lower score. In find_average, add up every score, then divide the total by how many scores are in the list:

average = total / len(scores)

Lists

A list stores multiple values in order. You can access items by index (starting at 0):

scores = [85, 92, 78, 95, 88]

print(scores[0])    # 85
print(scores[3])    # 95
print(len(scores))  # 5

For Loops

A for loop lets you do something once for each item in a list:

scores = [85, 92, 78]

for score in scores:
    print(score)

This prints each score on its own line.

Example Code

Here is a starting point. Fill in the TODO comments to meet the specifications above!

def find_highest(scores):
    # Start by assuming the first score is the highest
    highest = scores[0]

    # TODO: Compare each score against the running highest;
    #       if it is greater, make it the new highest!
    for score in scores:
        pass

    # TODO Return the highest score


def find_lowest(scores):
    # TODO
    pass


def find_average(scores):
    # TODO
    pass


# Print a list of scores, then computes and prints
# highest, lowest and average scores for the list
def evaluate_list(scores):
    print(f'{str(scores):^24}')
    print('-' * 24)
    print(f'Highest:{find_highest(scores):>16}')
    print(f'Lowest: {find_lowest(scores):>16}')
    print(f'Average:{find_average(scores):>16.1f}')


def main():
    evaluate_list([68, 1, 4, 60, 44])
    print()
    evaluate_list([91, 86, 97, 66, 19])
    print()
    evaluate_list([48, 0, 27, 60, 100])
    print()


main()

   [68, 1, 4, 60, 44]   
------------------------
Highest:              68
Lowest:                1
Average:            35.4

  [91, 86, 97, 66, 19]  
------------------------
Highest:              97
Lowest:               19
Average:            71.8

  [48, 0, 27, 60, 100]  
------------------------
Highest:             100
Lowest:                0
Average:            47.0
